Back Up Light Switch on a 1987-1988 Chevrolet V30: A Complete Guide
If your reverse lights have stopped working, the switch is the most likely reason—here's what you need to know.
- On automatic V30s, the back up light switch is part of the Neutral Safety Switch on the steering column; on manuals, it's on the transmission.
- Failure is common and symptoms are usually just that the reverse lights don't work.
- Standard Ignition is a recommended aftermarket brand known for reliability.
- This is a simple and affordable DIY repair that most owners can do in under an hour.
Is Your Back Up Light Switch Failing?
When a back up light switch starts to fail, the symptoms are usually straightforward. Because this is a simple part, failures are almost always related to the lights themselves and not how the truck drives.
- Reverse Lights Don't Work at All: This is the most common symptom. You shift into reverse, but the lights at the back don't turn on, even with good bulbs and fuses.
- Lights Work Sometimes: You might notice the lights flicker or only come on intermittently. Wiggling the gear shifter might make them turn on, which points directly to a worn or misaligned switch.
- Reverse Lights Are Stuck On: In rare cases, the switch can fail in the 'on' position. This will leave your reverse lights on all the time, which can confuse other drivers and drain your battery.
A Note for Automatic Transmission Owners
If you have an automatic transmission, the back up light switch is part of the Neutral Safety Switch (NSS). A failing NSS can also cause other problems, like your truck not starting in Park or Neutral, or only starting in Neutral. If you have both a no-start issue and a reverse light problem, the NSS is almost certainly the cause.
Choosing the Right Aftermarket Part
For a 1987-1988 V30, original GM parts are very hard to find. Aftermarket parts are the most practical and affordable choice. The quality of these simple switches is generally good for this truck.
Brand Tiers for Your V30:
- Standard Ignition: This is a well-known and respected aftermarket brand. For decades, they have been a go-to for reliable electrical parts that meet or exceed original factory quality. While some reviews note that quality can vary like with any brand, Standard is widely considered a dependable, professional-grade choice and a smart upgrade over basic parts.
- Replacement (and other value brands): These are budget-friendly options. For a simple switch on a work truck like the V30, a "Replacement" branded part will often get the job done without issue. However, the trade-off for the lower price can be a shorter lifespan or less consistent quality compared to a brand like Standard Ignition.
Pro Tip: Before you replace the switch, always check the bulbs and the "TURN B/U" fuse first. It's also a good idea to check the wire connections and grounds, especially on an older truck. This can save you from replacing a part that isn't broken.
Cost to Replace the Back Up Light Switch

|---|---|
| New Aftermarket Switch | $26.16 - $31.75 |
| Shop Labor | $75 - $150 |
| Total (Shop Repair) | $101 - $182 |
Frequently Asked Questions
Where is the back up light switch located on my V30?
It depends on your transmission. If you have an automatic with a column shifter, it's part of the Neutral Safety Switch located on the steering column, under the dashboard inside the cab. If you have a 4-speed manual transmission, the switch is screwed into the side of the transmission case itself, underneath the truck.
Is this a difficult part to replace myself?
No, this is a good DIY job for most owners. For automatic models, access is tight under the dashboard, but no special tools are needed. You'll need to remove a lower dash panel to see the switch on the steering column. For manual transmission models, you will need to safely raise the truck to access the switch on the transmission. The job typically takes less than an hour.
Are there any recalls for this part?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) for the back up light switch on the 1987-1988 Chevrolet V30. Any failure is due to the part's age and normal wear.
My reverse lights still don't work after replacing the switch. What now?
If a new switch, good bulbs, and a good fuse don't solve the problem, you likely have a wiring issue. Check the light green wire that runs from the switch to the back of the truck for any breaks or corrosion. Also, check the ground wires for the tail lights to make sure they are clean and have a solid connection to the truck's frame.
Technical Specifications
Location is dependent on transmission type (automatic or manual).
